CONSTITUTION:The outer periphery of the core 1 made of a non-combustible material is covered with a fire-resistant coating sheet 2 and the outer periphery thereof is covered with a coating material 3 with both water-resistant and weather-resistant properties in common to form a packing material. In this way, fireproofness, waterproofness, and weatherproofness are provided in common and also it is a dry substance with a specified shape and has elasticity in some extent as a whole and hence, it is easily charged into joints formed by a dry wall material (a). And it is also a fire-resistant packing material A excellent in workability without being left out.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention mainly relates to vertical joints formed by dry type wall materials, fire resistance and waterproofness for filling horizontal joints,
The present invention relates to a fireproof packing material that also has weather resistance.

[0002]

2. Description of the Related Art Conventionally, a joint treatment formed by a dry type wall material is a silicone type, polysulfide type moisture curing type, acrylic type, SBR type emulsion dry curing type wet irregular shaped packing material, or foam rubber, It is common to fill the joint with a dry type fixed packing material having elasticity such as polyvinyl chloride type, chloroprene type, chlorosulfonated polyethylene type, ethylene propylene type, and asphalt impregnated polyurethane type.

[0003]

However, in the case of the wet type irregular packing material as described above, it depends on the weather because of the wet type, a curing period is required, and a considerable skill is required for filling. The workability was extremely poor. Further, both of them have weaknesses in weather resistance and fire resistance, especially fire resistance, and particularly in dry wall materials having a fire prevention structure, a quasi fire resistance structure, and a fire resistance structure, improvement in fire resistance performance of joints has been a problem.

[0004]

In order to eliminate such drawbacks, the present invention covers the outer periphery of a core made of a non-combustible material with a sheet-like fireproof coating material, and further coats the outer periphery with a water resistant and weather resistant coating material. Since it is a packing material formed by coating with, it has both fire resistance, waterproofness, weather resistance, and is a dry type,
The present invention proposes a fireproof packing material which has a certain elasticity as a whole and is easy to be filled in a joint formed by a dry wall material and has good workability without falling off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the fireproof packing material according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory view showing a typical example of the fireproof packing material A, which comprises a core portion 1, a fireproof coating material 2, and a water resistant and weatherproof coating material 3.

FIG. 2 which is a partially enlarged view of FIG.
As shown in (a) and (b), the core portion 1 constitutes the central portion of the fireproof packing material A, and is made of rock wool,
It is preferable to use a non-combustible material having excellent fire resistance and fire resistance such as glass wool, ceramic wool and phenol foam, and having elasticity to some extent.

The fireproof coating material 2 is provided so as to cover the outer periphery of the core portion 1, and improves the fireproof performance and fireproof performance of the fireproof packing material A. It also hinders the progress of combustion without generating a large amount of toxic gas. Examples include flame-retardant and non-combustible coatings that are prepared by dissolving alkali silicate in water and adding clay, talc, and other pigments to it, and flame-retardant substances such as casein. Clay, talc, other pigments added to the above aqueous solution, or a mixture of these, oil, varnish, paint, enamel, etc. added to these, phthalic acid resin varnish, vinyl chloride, etc., chlorinated paraffin, etc. Is added, and antimony oxide is further added.

Further, the material for forming the heat insulating layer at the time of combustion is made by adding foaming raw materials (raw material for fire reaction chemical reaction catalyst, raw material for carbon generation, raw material for nonflammable gas generation), color pigment, film forming resin and the like. It is a thing. Among these, the carbon-producing raw materials are selected from carbohydrates and polyhydric alcohols, and these are carbonized by contact with a flame to form a heat insulating layer. Further, the carbon-producing raw materials have an acid group and produce an inorganic acid and an ester, and the inorganic acid is phosphoric acid. This is generated by thermal decomposition of catalysts and fireproofing agents. Furthermore, as a non-combustible gas generating raw material, dicyandiamide, melamine,
You may mix paraffin chloride etc.

Further, the fireproof coating layer 2 can be formed into a sheet shape, and the core material 1 and the fireproof coating material 2 are bonded to each other by
As shown in FIG. 2A, the self-adhesiveness of the fireproof coating material 2 may be used, but as shown in FIG.
It may be adhered via.

The water resistant and weather resistant coating material 3 coats the outermost periphery of the fire resistant packing material A and adds water resistance and weather resistance to the fire resistant packing material A. Examples of the material include plastic films and paints made of one or more of fluororesin, polyethylene terephthalate, polyethylene, polypropylene, nylon, cellophane, etc., or composites of these with paper, vinyl chloride resin sheets, and polyvinyl chloride-based materials. , Chloroprene type, chlorosulfonated polyethylene type, ethylene propylene type, asphalt impregnated polyurethane type, EPM, E
It is made of an elastic regular material such as PDM.

Examples of the adhesive 4 include an elastomer type epoxy resin, an isocyanate type emulsion such as methylene diisocyanate (abbreviated as MDI), a hot melt type, and its modified isocyanate such as urethane modified, buret modified isocyanate, isocyanurate. One type such as modified isocyanate is used.

For the adhesion between the fireproof coating material 2 and the water resistant and weather resistant coating material 3, the self-adhesiveness of the water resistant and weather resistant coating material 3 may be utilized as shown in FIG. 2 (a). As shown in FIG. 2 (b), it may be bonded via the above-mentioned adhesive 4.

Further, as the shape of the fireproof packing material A, as shown in FIG. 1, in addition to the columnar shape and the thin string shape as a whole, for example, the fireproof packing material A is formed into a cross sectional shape shown in FIGS. It can also be done. Further, FIG. 3 (g) is composed of a triangular prism-shaped short object. Of course, it is possible to have various shapes other than this example.

FIG. 4 shows an example of using the refractory packing material A. In the figure, a is a dry wall material and b is a wall foundation made of C-type steel material or the like. Figure 4 (a) shows the left and right drywall materials a.
The vertical joint portion formed between the two is filled with the fireproof packing material A by using elasticity, and FIG. 4 (b) is filled in the fitting portion of the dry type wall material a, and the joint and the fitting portion respectively are filled. The waterproofness, weather resistance, and fire resistance can be easily improved.

[0015]

As described above, according to the fireproof packing material of the present invention, the outer periphery of the core made of noncombustible material is covered with the sheet-like fireproof coating material, and further the outer periphery is covered with the water resistant and weather resistant coating material. Because it is a packing material formed by coating with, it has both fire resistance, waterproofness, weather resistance, and it is a dry type and has some elasticity as a whole,
Easy to fill the joints formed by dry wall material, and
It does not come off and has good workability. There are characteristics and effects.
